Bandpass filters transmit light only within a defined spectral band
ranging from less than one to many nanometers wide. They are used
in a wide variety of applications where spectral isolation is
required. Bandpass filters are preferable to monochromators because
of their higher transmission and better signal-to-noise.

Standard or customized features with different functions for the
special applications.

940nm Narrow Bandpass Filter compatibly used with 940nm LED light
or laser light source, which the image sensor only requires a small
bandwidth of the 940nm NIR light to for the black and white image.
